Email time zone indicator: +0000

An email sent from someone in the Zulu Time Zone (Z) time zone will have the time zone listed as "+0000" in the headers of the email. (However, "+0000" does not have to be in Zulu Time Zone, as other time zones could have the same UTC offset).

Where and when is Z observed?

Zulu Time Zone is often used in aviation and the military as another name for UTC +0:00. Zulu Time Zone is also commonly used at sea between longitudes 7.5° West and 7.5° East.

The letter Z may be used as a suffix to denote a time being in the Zulu Time Zone, such as 08:00Z or 0800Z. This is spoken as "zero eight hundred Zulu".
